The pot can only be found in the house of Alchemist <Naplus> in Eirel on the South Tyris continent. Because it is a precious item, it cannot be stolen. May also appear as a reward for returning Little sisters to the <Strange scientist>.
The item sprite ID for the pot is 555 (Row 16, Column 27) using the item sprite zero-based position system. It has a unique appearance, and no tint.
